Cnet is reporting today that 

“Microsoft and the One Laptop Per Child project announced Monday that Peru will be the first country to try out XO laptops running Microsoft Windows as part of a nine-month pilot program.”

Which comes as a bit of a surprise to me, as I haven’t read anywhere that Windows runs well enough on an XO to be effective. In fact, there’s even the chance that the XO’s hardware configuration need be changed in order to support Microsoft’s OS. I guess Peru, aiming to have towards 150,000 XO units distributed to kids and teachers by the end of the year, is a good testing ground for software variations. We’ll be watching with interest!
